Abstract

The invention discloses an Eclipse-based flash programming method, a plug-in and a system. The method comprises the following steps: determining first initialization information and second initialization information, wherein the first initialization information comprises serial number and Baud rate of a debug support unit (DSU), model number of a processor and a configuration value of a memorizer control register, and the second initialization information comprises communication serial number and Baud rate; initializing the processor according to the first initialization information; after the processor is initialized, performing handshake test on an upper computer and a lower computer according to the second initialization information; after handshake is success, downloading to-be-programmed data and programming into a flash of the lower computer according to programming configuration information, wherein programming configuration information comprises bit width, model number and an erasing area of the flash. By the method, the problems that the existing flash programming method is high in programming difficulty, tedious in operation, low in efficiency and low in universality are solved.

Description

technical field [0001] The invention belongs to the technical field of flash programming, in particular to an eclipse-based flash programming method, plug-in and system. Background technique [0002] Flash is an electrically erasable memory, which has the characteristics of low power consumption, large capacity, fast erasing and writing speed, and can be erased and programmed in the whole chip or by sector, so it is widely used in embedded systems. As a non-volatile memory, flash is usually used in the system to store program codes, constant tables, and some user data that needs to be saved after the system is powered off. [0003] At present, due to the particularity of the aerospace field, its flash programming method is still relatively backward, and most of them still use command-line tools to complete the programming, which requires memorizing the command line, and the operation is cumbersome and inefficient; moreover, various units in the domestic aerospace field The ...
